Specification of Letters Patent.

Patented Feb. 23, 1915.

Application filed May 25, 1914. Serial No. 840,682.

To all whom it may concern Be it known that I, FREDERICK WV. MOL- DENHAUER, a citizen of the United States, and resident of Oconomowoc, in the county of Waukesha and State of Wisconsin, have invented certain new and useful Improvements in Stanchions; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention refers to cattle stanchions and has for its object to provide a simple, economical and effective lock for the stanchion bar members.

A specific object of my invention is to provide a lock which, under strain of the animal, tends to grip more tightly, while at the same time it may be released by manual manipulation with slight exertion even though the bar members be under strain at the time.

Another object is to provide a locking dog having a U-shaped nose, the nose of which dog operates in conjunction with lugs of a tie-bar that is inverted T-shaped in cross-section, whereby the U-shaped or bowed nose will engage one of the notches upon the tie-bar, but will permit the companion notch to pass clear of said nose for engagement with a socket clip carried by one of the stanchion bars.

With the above and other objects in view the invention consists in certain peculiarities of construction and combination of parts as set forth hereinafter with reference to the accompanying illustrations and subsequently claimed.

In the drawings Figure 1 represents an elevation of a stanchion provided with a locking mechanism embodying the features of my invention, with parts and in section; Fig. 2, a plan View of the stanchion locking mechanism with parts broken away and parts in section as indicated by line 2-2 of Fig. 1; Fig. 3 a cross section of the locking mechanism with the locking dog member shown in full and the surrounding parts shown in section as indicated by line 33.

of Fig. 1; Fig. 4. a cross section of the stanchion locking mechanism with the tie-draw member shown in full and in its open position against a stop or clip, the section being indicated by line H of Fig. 1; Fig. 5, an inverted detailed sectional plan view illustrating the joint between the socket clip and stanchion-bar.

Referring by characters to the drawings, 1 represents the fixed stanchion-bar pro vided with a horizontally disposed top section 2, the throat portion of the stanchionbar being in hinge connection with a swinging stanchion-bar 3, each of said bars being formed from metallic strips that are preferably U-shaped in cross-section. The horizontally disposed top section of the fixed bar is riveted or otherwise secured to a saddle 4-, the side flaps 4: of which are folded over the bar to form a housing. The upper ends of the flaps are connected by a bolt 4, which bolt is linked to a shackle 5 that,

in turn, is in clipped union with a horizontally disposed frame-bar, not shown, whereby the stanchion is suspended. The throat portion of the fixed stanchion-bar is anchored by a series of links 6 in any suitable manner to the stall sill, not shown. The

free end of the swinging stanchion-bar 3.

has pivoted thereto a tie-bar 7, which tie-bar is in inverted T-shaped form in cr0ss-section, the rear end of the same being eX- panded to form a stirrup 8, which stirrup is utilized as a rest for the swinging bar when the stanchion members are open, being adapted to engage a vertical stall frame member, not shown. The free end of the tie-bar is in telescopic union with the top section 2 of the fixed stanchion-bar, as shown, having an upwardly projecting tooth 9 at its extreme end and an intermediate tooth 9. The intermediate tooth extends the full width of the T-shaped tiebar, while the end tooth 9 is of approximately the same width as the central web or stem 7 of said bar. The end of the top section 2 of the fixed stanchion-bar has secured thereto a clip 10, the lower wall of which is cut away to form a socket 10, into which socket the free end of the swinging stanchion-bar is adapted to nest when the stanchion members are closed. Thus a rigid joint between the stanchion members is effected at this point, whereby strain upon the locking mechanism is relieved.

A dog 11 is pivotally secured between the side flaps 4: of the saddle by means of a bolt 12, the position of which bolt, as shown, is above the line of travel of the tie-bar. The dog is provided with a locking nose 11, which locking nose is bowed or U-shaped in cross-section, as shown, whereby its lower edges are adapted to travel upon the horizontal web of the tie-bar, it being understood that the U-shaped nose is inverted and arranged to straddle the central web of said bar. The engaging face 11 of the dog nose is so tapered with relation to its fulcrum point and the face of the intermediate tooth 9 as to permit retraction of the dog from engagement of said face readily by a slight manual exertion. It will also be observed that, when the lower corner of the dog nose is in sliding contact with the tiebar, the end tooth 9 of said bar will readily slide through the throat portion of the dog nose, the said tooth being adapted to engage the upper bridge-piece 10 of the socketclip, whereby movement of the swinging stanchion member is limited when the latter is open to its extreme position. Thus the tie-bar forms a rigid connection between the stanchion members in either their closed or open position. The locking dog 11 is provided with a handle or tail-piece 11, which tail-piece projects beyond the saddle for ready manual manipulation of the dog. In order to hold the nose of the dog into its locking position with relation to the tie-bar, I provide ,a leaf-spring 13, which leafspring is secured to the bridge 10 of the clip, its free end being in engagement with the tail of the dog, whereby the latter is under spring-control in one direction.

From the foregoing description it will be apparent that, when the stanchion members are closed, the cheek-pieces of the dog nose will form locking engagement with the tooth 9, in which position said cheek-pieces straddle the central web of the bar and, in this locked position, the free end of the swinging stanchion is nested, as previously stated, within the clip socket. In order to open the stanchion, the locking dog 11 is manually manipulated, whereby its nose is lifted free from the intermediate tooth 9 of the tie-bar, limit of the movement of said dog being eifecte-cl by engagement of its tail portion with the bridge-piece 10 of the socket-clip. The swinging stanchion-member can then be drawn outwardly to its full open position and, in traveling to this position, the tooth 9 will pass through the U- shaped nose of the dog and limit the outward movement of the hinged stanchion member by its engagement with the bridgepiece of the clip, it being understood that, as soon as the nose of the dog is released from the intermediate tooth 9, said dog may be permitted to engage the upper tapered face of the tooth under spring pressure, whereby it will ride upon the horizontal webbed surfaces of the tie-bar coincident to an opening movement of the stanchion, as previously described.

I claim:

1. A stanchion comprising a U-shaped fixed stanchion-bar and a pivoted stanchionbar, the fixed stanchion-bar being provided with a horizontally disposed top-section, a suspension saddle secured to the horizontal section, a socket-clip secured to the end of said section for interlocking engagement with the free end of the swinging stanchionbar, a tie-bar in pivotal union with the free end of said swinging stanchion-bar having an upturned terminal tooth and an intermediate tooth, the terminal tooth being of less width than said intermediate tooth, a spring-controlled locking dog having a bowed engaging nose for engagement with the intermediate tooth, the end tooth being adapted to pass through said nose and engage the socket clip.

2. A stanchion locking mechanism comprising a saddle, an inverted U-shaped stanchion-bar section secured to the saddle, a socket-clip secured to the end of said section, a shiftable stanchion member arranged to nest within the socket-clip, a tie-bar pivoted to the end of the shiftable stanchionmember in telescopic union with the saddleearried stanchion-bar section, a tooth pro jecting upwardly from the free end of the tie-bar for engagement with the socket-clip, a spring-controlled dog in pivotal union with the saddle, and an intermediate tooth projecting from the tie-bar for engagement with said saddle.

In testimony that I claim the foregoing I have hereunto set my hand at Oconomowoc in the county of \Vaukesha and State of Wisconsin in the presence of two witnesses.
